DESCRIPTION

CELLULOSIC CLOSURE WITH ADHESIVE LABEL FOR PACKAGING OF

CARDBOARD WITH FLAPS AND PROCEDURE FOR USE

OBJECT OF THE INVENTION

The present invention refers to a closure for cardboard packages that incorporate flaps. It has the peculiarity that it is cellulosic, which facilitates the recycling of the packaging once it has been used, by not contaminating it with other types of materials.

The invention also refers to the procedure for closing cardboard packages with flaps using the aforementioned cellulosic closure.

TECHNICAL SECTOR

The present invention relates to cardboard and paper closures for cardboard packages containing flaps.

INDUSTRIAL APPLICATION

The developed system has a direct industrial application as a closing mechanism for all types of cardboard packaging with flaps.

Its design is versatile for all formats of this type of packaging, present in the transport and preservation of products from all kinds of industry sectors, facilitating the complete recycling of the packaging.

BACKGROUND OF THE INVENTION

The closure to preserve the privacy of the content characterizes the millions of cardboard packages that circulate daily around the world. Currently, almost all of these packages are closed using different varieties of adhesive closures.

Frequently serving as auxiliary components to these closures, staples, flanges and other aggressive elements are used that damage the packaging when removed.

Similarly, other variants of closures are known that try to avoid the damage that the adhesives cause the packaging, such as plastic material objects that fix the flaps of the cardboard boxes and sailboat strips.

DESCRIPTION OF THE INVENTION

The present invention describes a cellulosic closure with an adhesive sticker intended to be placed in cardboard packages that incorporate flaps.

It is made up of a clamp, configured in the shape of an “H”, and a sticker whose dimensions are larger than the clamp on at least two opposite sides.

The sticker comprises an adhesive surface, covered by a cover intended to be removed to access the area with adhesive, and a printing surface, intended to incorporate printed information related to the shipment or the contained product.

The "H" shape of the clip is designed so that each of the two openings it presents is designed to house one of the packaging flaps. With this form, a non-definitive pre-closure or initial closure is achieved.

The sticker is intended to be located, once the lid is removed, centered on the clamp, so that, when it protrudes, it is also located on the flaps, sticking to them and closing the packaging definitively.

In addition, the lid can incorporate at least one cut so that part of the lid does not come off when it is removed, preventing the adhesive in this area from being contacted. In this way, the adhesive of the sticker can be used to contact only the flaps of the packaging, without contacting the clip.

On the other hand, the lid can also incorporate two cuts, being divided into three parts, so that the central part is intended to be located on the clip, without being intended to be removed, while the two side parts are intended to be removed for the location of the adhesive areas of the sticker on the respective flaps. In this situation, it must be taken into account that if the lateral parts of the lid that are removed contact a single flap, that is, the case in which the cuts are parallel to the edges of the flaps, the security of the closure is not the same. guaranteed, insofar as the clamp could slide out from under the sticker, leaving the flaps joined only by the sticker.

On the other hand, the sticker preferably comprises at least one perforated line that is superimposed on the area of the cover intended not to be detached, so that when it is torn, the opening of the packaging is facilitated.

Optionally, it may comprise two perforated lines, each located on a flap.

Additionally, the invention also consists of a method of closing cardboard packages with flaps by means of the cellulosic closure that is described in claim 2 and that comprises the following phases:

a) Position the clip between the flaps of the box;

b) Detach the cover from the sticker;

c) Preposition the sticker on the clamp (1), without coming into contact;

d) Confirm that the clip is located within the area covered by the sticker; e) Position the sticker on the clip.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

As has been detailed, the developed system is a recoverable closure for cardboard packaging that preserves the inviolability of the content and identifies its recipient. It is made of paper and cardboard and replaces common adhesive closures. It is composed of two pieces: a clip (1) and a sticker (2), as shown in figure 1

In this figure 1 it can be seen that the clip (1) is made up of a strip of folded cardboard, so its manufacture only requires making these folds from the fold lines.

As shown in figure 1, the sticker (2) consists of an adhesive strip that, on one side, incorporates a cellulosic printing surface intended to present the appropriate shipping information, while on the other side it incorporates the adhesive, covered by a cover (5) that must be removed to place the sticker (2).

Figure 2 shows that the cover (5) has cuts (6) so that, when removed, the central area is not adhesive, but remains covered with part of the cover (5) so that the adhesive does not contact the clamp (1). In this way, the cuts (6) can consist of a rectangular area with the same objective that the adhesive does not come into contact with the clamp (1) when it is placed on it but that it becomes fixed to the packaging on all four sides, increasing the closure security.

In addition, the sticker (2) also has perforated lines (4) that are superimposed by the area of the sticker (2) that still retains part of the cover (5). These perforated lines (4) are intended to be torn to facilitate opening of the package. These perforated lines (4) can be reduced to a single one, although they are preferably two, one on each of the flaps (3).

In this way, to proceed with the closure of the packaging, it is only necessary to place the clip (1) in the appropriate position of the packaging by capturing the two flaps (3) and then fix the sticker (2) to the packaging on the clip (1) , leaving it centered under the sticker (2).

As shown in Figure 4A, one way to apply the sticker is with the perforated lines (4) parallel to the line where the flaps join. To open the packaging, simply tear the sticker (2) along at least one of the perforated lines (4) and access the clip (1) to separate it from the flaps (3), without causing damage in the process.

In any case, as shown in figure 4B, the sticker (2) can also be fix to the packaging so that the perforated lines (4) are located on the two flaps (3) of the packaging, with the only difference that to open it, the sticker (2) would have to be torn along the two perforated lines (4) and thus access the clip (1) to separate it from the flaps (3).

In this way, the clamp (1) is reusable in order to be able to close another package simply by printing the corresponding sticker (2).

Finally, indicate that the present invention should not be limited to the embodiment described here. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
